In conductive aluminum tubes, the faster the ions move, the higher the conductivity will be.In aluminum electrolysis production, the conductivity of electrolytes is affected by many factors:
It is related to the temperature of electrolysis.The higher the temperature is, the faster the ions move and the higher the conductivity is.However, high electrolysis temperature will lead to reduced current efficiency, increased energy consumption and raw materials, so the benefits of improving conductivity cannot compensate for reduced current efficiency and other losses.
It is related to the molecular ratio of Aluminium Hollow Rectangular conductor.The conductivity increases with the increase of molecular ratio.
3 is related to the concentration of Al2O3.The conductivity of electrolyte decreases with the increase of Al2O3 concentration.
(4) with the carbon particles in the electrolyte.When the electrolysis temperature is high, the carbon particle content in the electrolyte will increase, and the increased carbon content will not only reduce the conductivity of the electrolyte, but also reduce the moisture of the electrolyte to Al2O3 crystal, thus causing alumina precipitation.
(5) related to additives in electrolytes.The influence of additives on the conductivity of cryolite can be divided into two types.Adding lithium fluoride and sodium chloride to electrolyte can improve the electrical conductivity of electrolyte, especially lithium fluoride has remarkable effect.Adding calcium fluoride and magnesium fluoride to the electrolyte can reduce the conductivity of the electrolyte, but they can make the carbon residue good separation, reduce the content of carbon particles in the electrolyte, can make the conductivity of the electrolyte better, indirectly increase the conductivity
